Thats ashame. Was it a older guy? Not to generalize,but seems the older men tend to take things a lot more personal. Personally I would have just Covered it up, and continued shopping with a " Print " mark. Im asuming OC holsters dont make good CC holsters lol
And if that wasnt good enough, just left and told them I would never be back to shop in there again. Along with a letter to the store.
